[Q] "working phone", but black screen after the boot logo

Hello guys,
some days ago my phone was permantly booting up in the recovery mode nothing else was possible. As I was on road and couldn't access internet anywhere I just tried to do some wipes, which then made my phone not show anything. I guess the reason that it didn't boot up anymore was that the battery was fully drained. When I was finally back home I was able to charge my phone but then the following happend:
I can start my OPO, see the android logo and then it turns black, but it fully boots up. I mean I can even click the touchscreen and hear some touch reactions/sounds. Also I'm able to turn up/down the volume and hear my phone. Furthermore I'm also able to do the "V-gesture" to turn on the flashlight. When I boot up into fastboot mode I also see the message "fastboot mode" + the little cyanogen face.
All in all everything seems to work, aside that I dont see anything else than dark after the logo.
I tried flashing new roms, stock reset, like seriously anything, but I can't get my phone to work probably again.
Does that mean that my phone got some hardware problems, maybe the touchscreen?
Help is appreciated, thanks in advance!
btw: English isn't my first language, so please excuse any mistakes.

You'll have to try flashing completely stock CM11 rom or CM12 rom, img by img in fastboot..modem, boot, system etc. I helped a friend who had this kind of problem. Probably not the cleanest way, but at least it works.

Already did that 3times using different methods. Stock CM11, CM12 and colorOS

I have a similar problem, did you manage to fix it? And if so, how?
Thanks,
Capelare.

Samsung galaxy core 2[SM-G355H] Problem

So.. I have this nice phone, but with broken glass[touch works anyways] So i was with a little mod custom rom, but i wanted to have the stock rom cuz its much clean, etc you know.. So i installed it, trough Odin, but.. the problems started. It stays on the splash screen Much time. Then, it boots up, but i can't click nothing. And then after a few seconds, it reboots. That's the problem. I tried to install CWM, ok, installed it but it stays only on splash screen. If someone can help, please do it
PS: Also, I Can go to download mode only.

Bricked!

After installing blisspop (or I don't really remember), I realized that WiFi wasn't working and neither was bluetooth so I decided to flash Extended Stock Kernel kernel, first with flashing the boot, then flashing the zip from recovery mode and even after that, the result was the same. It didn't work. Later on I went to the Phantom kernel's page and flashed that without checking that the kernel was meant for 4.4 and it bricked my device. Now, whenever the phone starts, it shows the Phantom kernel boot at start with its logo without any led light appearing below and due to that I'm unable to go into either flashmode or fastboot. It keeps restarting the Phantom boot at start and doesn't go any further. Please help!
EDIT: A more detailed version that I wrote a few months ago to the kernel's developer.

Previously I had my Xperia L reset on stock ftp then flashed the Extended Stock Kernel on it. Since the wifi wasn't working, I tried to download R17 and flashed it through CWM and now the phone keeps restarting on the Phantom Logo. It shows the logo, waits for about 10 seconds then restarts and the same keeps repeating. I saw it was for Kitkat but then too I insisted on installing. I can't access neither bootloader nor recovery mode. The light which comes when the Phantom Logo pops doesn't appear either. Can you help me please? Anything would be greatly appreciated. I know I did a stupid thing but I really don't want to give up on this device.

[Completed] I think I have bricked my SM-T320, help

model: sm-t320 wifi only, just flashed cm13 nightly, i believe it was the one released on the first of February 2016, the tablet was working okay sometimes a bit laggy but that is expected with the nightly not fully developed or whatever. i installed and am still using cm13 on my tablet but i installed it on my friends tablet which is the exact same tablet, color and all, and this happened: it shut of by itself and when i tried to turn it back on it wouldnt. i plugged it in and the battery charging icon turned on but it was only the icon with the loading circle image in the middle. so i let it charge for a good six hours and during that the screen stayed on with the same image. when i unplugged it, after about two seconds the screen dimmed and started flashing on and of as if there was a loose connection. then it just shuts off. when it is unplugged i cant do anything, (turn on, download mode, recovery) the screen just stays blank. when i have it plugged in i can access the first boot screen displaying "samsung galaxy tab pro" and it will not go any further. i can also access download mode perfectly. i cannot access recovery mode, it just goes straight to the first boot screen. i tried flashing the stock rom and was unsuccessful. either because the computer was not supplying enough voltage/amps to keep the tablet running or it just simply would not boot. the flash was successful each time i tried on odin but the same issues happened on the tablet each time. i did not install Gapps because he just wanted to try it out quickly and maybe keep it or go back to stock if (that helps). i believe that is all i know. please help me!

[Completed] Kindle Fire HD7 stuck on TWRP boot logo after CM13

help needed !!
I have a KFHD7(tate) and had been running CM12.1 for a while with only an occasional update using the nightly builds, I only updated occasionally as the unit would not always turn on at the first attempt and would stick at the CM boot logo, after switching it off and back on the unit would run quite smoothly, however none of the updates seemed to cure the problem.
I noticed that there was a new release 'cm-13.0-20160218-UNOFFICIAL-tate' which I flashed via TWRP along with 'open_gapps-arm-6.0-stock-20160301', these were flashed at the same time.
after a reboot the KFHD7 worked fine with no apparent problems, I then downloaded one of the dark themes,(not sure exact one) and this seemed ok at first, I entered the settings screen and only a few words and graphics were visible!
I rebooted back into TWRP recovery and performed a factory reset from within TWRP ... big mistake, now the unit only boots to the blue TWRP boot screen and blinks off after a few seconds it is stuck in a loop and I dont know how to recover it, I have tried the usual combinations of holding the power and vol buttons but still comes on the same .. any suggestions would be appreciated (dumbed down solutions please as not that techy, but can muddle through if step by step instructions)
